COW-MILKER.

SPECIFICATION forming part of Letters Patent No. 675,414, dated June 4,1901.

Application filed November 2, 1900. Serial No. 35,269. (No model To @ZZ11j/tom, it may concern.-

Beit known that I, REUBEN D. ROTH, a citizen of the United States,residing at Mummasburg, in the county of Adams and State ofPennsylvania, have invented a new and useful Cow-Hillier, of which thefollowing is a specification.

My invention relates to milking-machines, and more particularly to thatclass which are adapted to be applied to and manipulated by the hand ofthe operator; and it has for its object to produce a device of this kindwhich will be strong and durable and can be applied to eitherhand,wherebythe operation of milking can be performed with less exertion orpressure from the fingers or hand.

Vith the above object in view my invention consists in the improvedconstruction and novel arrangement of parts of the same, as will behereinafter more fully set forth.

In the accompanying drawings, in which the same reference-numeralsindicate corresponding parts in each of the views in which they occur,Figure l is a perspective view of my improved milking-m achine inposition for use. Fig. 2 is a longitudinal sectional View of the same,the parts being shown open in full lines and closed in dotted lines.Fig. 3 is a transverse sectional view, and Figs. 4 and 5 are perspectivedetail views.

My improved milking-machine comprises two members l and 2, which arehinged or pivotally secured together at one end in any suitable manner,as by means of overlapping ears or projections 3 and et. A suitablehinge or rivet 5 is passed through perforations 6 in said ears andpermits of the upper ends of the two parts being moved toward each.other. By providing a series of holes in the ears of one orboth of themembers the machine may be adjusted so as to be properly applied toteats of different sizes.

The two parts l and 2 may be formed from any suitable material,preferably flexible, as vulcanized rubber, which will permit of theirbeing adapted to the purpose for which they are intended. Incross-section they are semicylindrical, so as to partially surround theteat, and the upper ends are provided upon their inner faces withtransversely-arranged corrugations 7, which are preferably of differentlengths, the alternate corrugations being long enough to cause the endsof one member to overlap the ends of the shorter corrugations of theother member, thereby causing the two members to completely encircle theteat and force out all of the milk. The faces of these corrugationsmaybe plain or smooth; but I prefer to provide them with lines orindeutations 8, which may cross or intersect each other in any desiredmanner.

One of the members is provided at its upper end with a D-shaped handleupon the exteriorsurface for the reception of the thumb of the operator,and the other member is provided with a substantially B-shaped handlefor the reception of two lingers of the operator, said handles beingpreferably arranged diametrically opposite each other and substantiallymidway of the circumference of each member, whereby the machine isadapted for use by either hand.

In using my improved milking-machine it is properly adjusted to the sizeof the teats upon which it is to be used and then placed on the hand ofthe operator by passing the thumb and fingers through the handles orloops. This will cause the two members to lie directly across the palmof the handand project a suitable distance above and below the same toavoid the necessity of the hand coming in contact with the udder or themilk. The members are then separated by the move* ment of the thumb andlingers and placed upon the teat and forced into contact therewith. Inthis manner the danger of pollution to the milk from contact with thehand of the operator is avoided and more cleanliness is secured. Byproperly adjusting the parts so that they will completely collapse orclose the teat the cow'can be milked perfectly dry, thereby avoiding theobjection of only partially removing the milk from the udder. It willalso milk cleaner than the hand, as it avoids the cavity underneath thethumb and within the palm of the hand. It can be quickly cleansed andwill perform the operation of milking with less power and energy than isrequired with the natural hand.

Having thus fully described my invention, what I claimv as new, anddesire to secure by Letters Patent, is

l. In a milking device, the combination, with two substantiallysemicylindrical mem- IOO bers, the upper end of each of lwhich isprovided with a holding means and the lower end is provided with aperforated 4ear projecting from each edge, the ears of one memberoverlapping those of the other member, and a rivet removably secured insaid perforations whereby the device may be adjusted for use,substantially as described.

2. As a new article of manufacture, a milking device comprising twosubstantially semieylindrical members having perforated overlapping earsat their lower ends and formed upon their inner faces withtransversely-exm tending corrugations and having their edges
